章 306: 404 Research Institute

In a certain sea area, a submarine began to sink rapidly.

In an instant, it had descended to the ocean floor over two thousand meters deep.

"Activate the photic sensors!"

Aboard the submarine, a man dressed in military attire with a scar across his face, intently stared at the monitor and spoke slowly.

With the activation of the detection equipment, the screen displayed countless bright points, resembling stars.

"Target detected, ranging from one thousand to two thousand in number..."

"Release the plankton, prepare to lure..."

Following the scar-faced man's order, a large number of tiny plankton were released.

On the screen, many bright points began to move in response to the appearance of the plankton.

At the same time, a suction force emerged from beneath the submarine, and a vast amount of seawater was drawn into it.
